Not piling on here, but I'm pretty sure Goering wasn't anywhere near Berlin at the end of the war either. He spent his final days far away from Berlin in a bunker, until Hitler had him arrested for suggesting that he take command. What are the chances he would have an abandoned Mercedes left sitting around intact?
This story is obviously PHONY starting with the idea that an American GI was in Berlin when it was being stormed by the Soviets. I call BULL on this story and am amazed by the historical ignorance of the NBC reporters.
